To evaluate whether the neutrophil-to-lymphocyte ratio (NLR) predicts survival in patients with unresectable hepatocellular carcinoma (HCC) before and after transarterial chemoembolization treatment.Clinical and laboratory data for 145 consecutive patients undergoing transarterial chemoembolization for unresectable HCC during 2001-2004 were analyzed retrospectively. The NLR was recorded before and 3 days after treatment.The pretreatment mean NLR was 3.3; 59 (40.7%) patients had an elevated NLR (≥ 3.3). The median survival of patients with a high NLR was 8 months (range 1-28 months) compared with 12 months (range 2-41 months) for patients with a normal NLR; a significant difference was found in overall survival (log-rank test, P = .001). The NLR was increased in 127 (87.6%) patients after transarterial chemoembolization and was decreased in 18 patients; the increase indicated better outcomes (log-rank test, P = .006). Age (≥ 49 y), high NLR, decreased NLR after treatment, large tumor (≥ 5 cm), vascular invasion, and elevated serum α-fetoprotein (AFP) level all were predictors of poor survival. Multivariate analysis showed that a high NLR (P = .041) and vascular invasion (P = .040) were independent factors for predicting worse survival.A high NLR independently predicts poor survival in patients with unresectable HCC undergoing transarterial chemoembolization treatment, and an increased NLR indicates a better outcome than a decreased NLR for patients after transarterial chemoembolization.
